To all 'whom t may concern.'

Be it known that I, ALBERT BIE, a subject of the Kingdom of Norway,residing in Winterthur, Canton of Zurich, Switzerland, have inventedcertain new and useful Improvements in Engine Construction, of which thefollowing is a full, tr'ue and complete specification.

Ihe invention relates to internal combustion engine constructionembodying improvement in the assemblage and manufacture of thecombustion cylinder and special facilities for cooling the same andaccommodating the thermal expansions and contractions, as willhereinafter be made apparent to those skilled in the art.

In the accompanying drawings:

Figure 1 is a vertical section through the head end of a cylindercontaining the improvement in one of its forms;

Fig. 2, a plan thereof;

Fig. 3, a fragmentary vertical section of another form;

Fig. f1, a horizontal section on the line IV-IV of Fig. 3;and

Fig. 5 is a View of the engine, partly in elevation and partly invertical section.

The water-jacket 1 is provided at its head end with four lateral lugs13, which vare clamped to the upper ends of tie rods or columns `2rising from the base 14, and its lower end is provided with similarguide lugs 15 also engaged to the rods and capable of movement thereonto accommodate lengthwise expansion of the water-jacket wall. The waterjacket cylinder is thus relieved of longitudinal stresses and its headbearing the valve organs is held in fixed position with relation to thecrank shaft 36 under all conditions.

The upper portion of the water-jacket which is swelled outward, as shownat 16 is formed with a depending, reversely-turned inner wall 17,forming the circular boundary of a head-receiving recess, and the lowerend of this wall, being appropriately bra-ced as indicated, forms anannular seat 8 to receive an outwardly directed head flange 19 on theupper end of the cylinder liner 6. The latter is a separately made partintended to complete the water jacket and surround the 'combustion spaceand the reciprocating piston 20. At its lower end the liner 6 is :fittedto the water jacket in any suitable manner, which will retain thecooling water and accommodate such difference of expansion as may occur.

The head 3 is hollow for circulation of water, entering at 3a andleaving at 3b, and 1s intended to carry the usual valve organs, asindicated by the valve sockets 4. This head is set into the upper yendof the water- ]acket, bearing against the top of the head flange of theliner, with which it forms a tight seal'against leakage from thecombustion space, by means of interengaging facings 7, with or without agasket. The top of the head is formed with an outwardly extending liange21 overlying the top of the water-jacket, to which it is fastened bybolts 5. These bolts press the'head and the liner fiange together andagainst the seat 8, and,

permit the ready removal of the head without disturbing the columns 2 ordisconnecting therefrom the cylinder part l. The liner 6 can also bereadily withdrawn if desired when the head has been removed.

The liner flange 19 is preferably recessed, as indicated at 9, in orderthat it may be cooled by access of the coolin water to its interior, andthe recessing of t e flange may be in the form of a continuous annulargroove recess, as shown in Fig. 4, or of separate cavities,l assuggested in Fig. 1; and in either event the interior of the flange maybe placed in communication with the waterjacket space by openings 10through the wall 17, above the seat 8. Furthermore, as shown in Figs. 3and 4, openings 12 may pierce the under side of thehead flange, openinginto the Water jacket space below the seat. In this construction the uperiportion of the water jacket space is pre erably divided off, eitherpartially or entirely, by a wall 22 connecting the lower edge of thewall 17 with the outer wall of the water-jacket, thus facilitating thecirculation of water from one part of the water-jacket space to anotherand through the interior of the flange 19. The lip 11 in Fig. 3obstructs escape of water through the crevice between the head and waterjacket.

From the foregoing description it wllbe apparent that the principle ofthe invention is not confined to the specific construction abovedescribed, and that various modifications, changes in proportion andalterations may be made therein without departing from the scope of thefollowingfclaims.

I claim:

l.' An internal combustion engine comprleing a base, a set of tierodsrising therefrom, a combustion cylinder having a water-jacket betweensaid rods and detachably secured to the latter by its upper end, and acylinder head fastened to the cylinder independently fthe tie rods andremovable without disturbing the connection of the cylinder thereto. 4

2. An internal combustion engine comprising a base, a set of tie rodsrising therefrom7 a combustion cylinder having a water-jacket betweensaid rods and detachably secured to the latter, a cylinder head having acylindrical hollow body set within the upper end of the cylinder and adownwardly facing shoulder at its top, and bolts assing through saidshoulder into the cylin er end and permitting the removal of thecylinder head without disturbing the connection of the cylinder with thetie rods.

3. In an internal combustion engine, the combination of a base, a set oftie rods rising therefrom, a water-jacket between and detachably securedby its upper end to said tie rods, a separate cylinder liner terminatingat its upper end below the top of the water-jacket, a cylinder headcomprising a cylindrical hollow body set into the upper end of thewater-jacket against the end of the cylinder liner, and bolts holdingthe cylinder head in place and permitting removal of the same outwardlythrough the top of the water-jacket.

4. In an internal combustion engine, a water-jacketed cylinderdetachably connected by its upperl end through tie rods with a baseplate and having its head portion constituted of outer and inner parts,the outer of said parts being integral with the waterjacket and theinner part being fastened independently of the tie rods and removableoutwardly from the top of the cylinder.

5. In an internal combustion engine, the combination of a base, a set oftie rods rising therefrom, a water-jacket between and secured by itsupper end to said rods, said Water-jacket having a seat below its upperend, a cylinder liner having a ange resting on said seat, a cylinderhead comprising a cylindrical hollow body set into the upper end of thewater-jacket and bearing against the end of the cylinder liner, andmeans separate from the tie rods for pressing the cylinder liead andliner against said seat.

6. In an internal combustion engine, a water-jacket having an inner wallat its head end forming an inner boundary of the waterjacket space, anda seat on said wall in wardly of the end, a cylinder liner having aflange against said seat, a cylinder head comprising a cylindricalhollow body set into `head end, a liner having a flange bearing againstsaid seat, a head comprising a cylindrical hollow body set into thewater-jacket and bearing against the liner flange, and means engagingthe head for pressing the same and the liner flange t0 the seat, saidhead and liner being free for radial expansion in theI water-jacket.
